Answer:
kinetic energy is a energy of motion. At a given temperature, individual particles of a substance have a range of kinetic energies. The motion of particles theoretically ceases at absolute zero.

Explanation:
The normal hemoglobin is made up of heme and globin. The protein, globin is in turn made up of four polypeptide chains which include two alpha and two beta chains.
The gene gene responsible for the creation of the beta globin chain is located on the short arm of chromosome eleven. It is called the HBB gene. Many mutations occur on the HBB gene and a mutation on this gene produces abnormal hemoglobin like HBS, hbc, and hbe. HBs causes sickle cell anemia.
In sickle cell anemia, there is an alteration of the genetic code, leading to the substitution of a single amino acid where glutamic acid is replaced by valine in the sixth position of the beta chain.
In the mRNA, the change converts a glutamic acid codon(GAG or GAA) to a valine codon(GUA, GUC, GUU or GUG).
Sickle cell anemia is caused by a transversion that leads to a missense mutation.
Answer & Explanation:
At higher elevations, water condenses from the air and produces clouds, which often blanket lofty peaks and completely obscure them. As the clouds get saturated with moisture, rain and snow fall. The precipitation, when combined with the strong winds, results in frequent stormy weather.
Viens. :) Goodluck on your homework.
